How to judge the quality of circular colored copper plate label paper?

To judge the quality of circular color copperplate label paper, it can be considered from the following aspects:

1. Material composition and quality

Surface material: high-quality round color copper plate label paper usually uses high-quality coated paper as surface material, which has a smooth surface and good printability and color reduction.

Coating: The surface coating should be uniform and delicate, which can effectively protect the surface of the paper, improve the printing effect, and increase the durability of the label.

Adhesive: The choice of adhesive and coating quality directly affect the adhesive performance of the label. A good adhesive should have appropriate viscosity and stickiness, which can be firmly stuck to the surface of the object and can be easily removed when needed.

Backing paper: The backing paper should have good release performance, that is, the peeling force between the adhesive and the adhesive is moderate, neither easy to fall off nor too adhesive, so that the label can be smoothly peeled off and used.

2. Printing effect

Color brightness and clarity: high-quality round color copperplate label paper should have good printing effect, bright color, high clarity, and can accurately restore design patterns and text.

Printing accuracy: The printing accuracy of the label is also one of the important indicators to measure its quality. High-quality label paper should be able to maintain accurate alignment and clear edges of the pattern and text during the printing process.

3. Physical properties

Water resistance and wear resistance: Good label paper should have certain water resistance and wear resistance, and can maintain the integrity and clarity of the label in wet or friction environments.

Tear resistance: The tear resistance of the label paper is also one of the important parameters to measure its quality. High quality label paper should have strong tear resistance and is not easy to be damaged during transportation or use.

4. Environmental performance

With the improvement of environmental awareness, environmental performance has also become one of the important standards to measure the quality of label paper. High-quality round colored copper label paper should comply with relevant environmental standards and regulations, and do not contain harmful substances or volatile organic compounds (VOCs) and other pollutants.

5. Supplier reputation and certification

Supplier reputation: Choosing a supplier with good reputation and reputation is an important prerequisite for ensuring the quality of label paper.

Certification and qualification: high-quality label paper suppliers usually have relevant quality certification and qualification certificates, such as ISO9001 quality management system certification, these certifications and qualifications can be used as an important reference basis to measure the quality of their products.

In summary, to judge the quality of circular color copperplate label paper, it is necessary to comprehensively consider the material composition and quality, printing effect, physical properties, environmental performance and supplier reputation and certification. In the actual purchase and use process, you can choose the appropriate label paper products according to the specific needs and actual conditions.
